Walmart offers the refurbished Samsung 55" Nano Crystal 4K LED-Backlit UHD Smart Television, model no. UN55JS700D, for $599.99 with free shipping. That's tied with our April refurb mention as the lowest total price we've seen for a 55" Samsung 4K TV. (It's also $297 below the best price we could find for a new one.) It features a native resolution of 3840x2160 (4K), 120Hz refresh rate, quad-core processor, screen mirroring, 802.11ac wireless, Internet Apps (like Netflix, Hulu Plus, and YouTube), three USB ports, and four HDMI ports.
